Fix leaky handling of `scm_take_locale_{symbol,string} ()'.

* libguile/strings.c (scm_i_take_stringbufn, scm_i_c_take_symbol):
  Remove.
  (scm_take_locale_stringn): Rewrite in terms of `scm_from_locale_stringn ()'.

* libguile/strings.h (scm_i_c_take_symbol, scm_i_take_stringbufn):
  Remove declarations.
